Parts/Kit Overview

The R&D Yamaha FX-140/FX CRUISER Stage 1 Performance Kit was developed to significantly improve handling and overall engine performance with easy to install entry-level performance parts. Each component part listed can be installed and used as a stand-alone product. The R & D FX-140 Stage 1 Kit has been in the testing and development stages for two years, creating a ride plate and sponson kit combination that will eliminate the annoying hunt or bow search noticed while riding at top speeds. The addition of the R&D Stage 1 Performance Kit will transform the FX-140 or FX-140 Cruiser into one of the best handling watercraft on the water. Order up some fun today!

  • The R&D Solas 13/19 Impeller will increase hook-up, acceleration and top speed performance.

  • The R&D Power Plenum Breather Kits unique design will flow much more air than the O.E.M. filter. O.E.M. filters are notorious for becoming over oil saturated causing sluggish low-end power and a loss of up to 500 RPMs! The R&D replacement breather will never over oil saturate, making it the only replacement choice! Easy to install in 5 minutes, adds a great sound tone, and adds RPMs.

  • The R&D Power Plenum Twin Flame Arrester Kit will add a noticeable gain in low-end throttle response over the O.E.M. flame arrester, and adds a high performance sound to the FX-140!

  • The R&D pump shoe sealer kit will seal up the FX-140s pump shoe and pump inlet to promote reduced cavitation, much better hook-up, and add top speed performance.

  • The R&D FX-140 pump cone was designed to increase bowl pressure in the pump venturi nozzle. The R&D pump cone reduces cavitation and increases pump efficiency.

  • The R&D FX-140 Aquavein Intake Grate will reduce overall pump cavitation and add a 2-3 mph average top speed in choppy water conditions over the O.E.M. intake grate.

  • The R&D FX-140 steering nozzle kit was developed to work in conjunction with the Solas 13/19 or higher degree impellers! The larger bore and lack of straightening veins will help to raise RPM levels through tight turns!

NOTE: For proper RPM and performance of the Solas 13/19 Impeller, it will be necessary to bore the O.E.M. Nozzle out plus 1 mm (.040).
